All of these isolates were inhibited at 0.5 mg/L of tigecycline. For S. pneumoniae isolates, 72% were not susceptible to penicillin (69% intermediate and 3% resistant) and 96% were not susceptible to azithromycin. Among the 178 isolates resistant to azithromycin, 53 isolates (30%) had the M phenotype and 70% had the cMLS( B) phenotype. The rate of nonsusceptibility to ertapenem, telithromycin, moxifloxacin, and quinupristin-dalfopristin in S. pneumoniae was 3%, 2%, 1 %, and 57%, respectively. For H. influenzae, 36 (60%) were not susceptible to ampicillin, among which 31 possessed beta -lactamase. A high rate (8.3 %) of H. influenzae isolates with beta-lactamase-negative and ampicillin- resistant phenotype was found. All H. influenzae isolates were susceptible to azithromycin, but 40% of them were not susceptible to clarithromycin. Ninety-eight percent (44 isolates) of M. catarrhalis possessed beta- lactamase. All three fluoroquinolones tested were highly active (MIC90 <= 0 .12 mg/L) against H. influenzae and M. catarrhalis. |
